What is the term for the visual examination of a joint?

The term that refers to the visual examination of a joint is arthroscopy. This procedure involves the use of an arthroscope, which is a small camera-like instrument that allows a physician to see inside a joint and diagnose potential issues. It is commonly used for conditions affecting various joints, including knees, shoulders, and hips.

Other options do not pertain to the examination of joints. Rhinoscopy is an examination of the nasal passages and sinuses, endoscopy generally refers to the examination of the interior of the digestive tract using an endoscope, and colonoscopy specifically pertains to viewing the colon. Each of these procedures is focused on different areas of the body, which distinguishes arthroscopy as the correct term for joint examination.
